  • 容值:470pF(标称值,型号中“471”表示47×10¹pF)
  • 精度:±10%(型号中“K”为精度代码)
  • 额定电压:50V DC(型号中“500”表示50V)
  • 温度系数:X7R(风华通用X7R系列标识)
  • 系列:B系列(风华中高压通用MLCC系列)

该产品兼顾小封装、中容值与温度稳定性,适配多数电子电路的滤波、耦合、去耦需求,属于消费级通用型器件。

二、封装与物理特性

0201封装为超小型表面贴装设计,满足便携式设备的微型化需求:

  • 尺寸:0.02英寸×0.01英寸(0.508mm×0.254mm,长×宽)
  • 典型厚度:0.25mm(含端电极,不同批次略有差异)
  • 端电极:无铅锡银铜(Sn-Ag-Cu),符合RoHS 2.0、REACH及无卤素标准,支持回流焊工艺
  • 包装:编带式(tape and reel),标准盘装数量为10000pcs/盘(部分规格为5000pcs/盘)

封装特点:小体积高集成度,适合高密度PCB布局,可有效减少电路占用空间。

三、电气性能关键参数

3.1 容值与精度

  • 标称容值:470pF
  • 精度等级:±10%(K档),实际容值范围为423pF~517pF
  • 容值偏差:符合IEC 61071标准,25℃下偏差≤±10%

3.2 电压与功率

  • 额定直流电压(VR):50V DC(最大连续工作电压)
  • 交流电压(VAC):峰值≤35V(交流降额后使用,避免绝缘击穿)
  • 功率:无额定功率,需根据实际电路功耗降额设计

3.3 温度与频率特性

  • 温度系数:X7R(行业标准定义:-55℃~+125℃范围内,容值变化≤±15%)
  • 损耗角正切(DF):1kHz、25℃下典型值≤2.5%,125℃下≤3.5%
  • 绝缘电阻(IR):25℃下≥10⁴ MΩ·μF,125℃下≥10³ MΩ·μF
  • 谐振频率:典型值≥50MHz(100pF~1000pF范围X7R MLCC的典型谐振频率)

四、可靠性与环境适应性

风华高科作为国内MLCC龙头企业,该产品通过多重可靠性测试,满足消费电子及通用工业场景需求:

  • 耐焊接热:260℃回流焊3次(符合IPC/JEDEC J-STD-020标准),容值变化≤±5%
  • 温度循环:-55℃~+125℃循环1000次,容值变化≤±10%
  • 湿度耐久性:85℃/85%RH环境下1000小时,容值变化≤±10%,IR≥10³ MΩ·μF
  • 寿命:额定条件下(25℃、额定电压),平均无故障时间(MTBF)≥10⁶小时

环境适应性:符合工业级环境要求,可在-55℃~+125℃范围内稳定工作。

五、典型应用场景

0201B471K500NT因小封装、中容值及X7R温度稳定性,广泛应用于:

  1. 便携式电子设备:智能手机、智能手表、蓝牙耳机的信号滤波、耦合电路
  2. 消费电子:平板电脑、智能家居设备的电源去耦、噪声抑制
  3. 工业控制:小型传感器模块、PLC辅助电路的信号处理
  4. 通信设备:低功率无线模块(如WiFi、蓝牙)的射频滤波

注意:该产品为消费级,不建议用于汽车电子(需AEC-Q200认证)、医疗设备(需医疗级认证)等特殊场景。

六、选型与使用注意事项

  1. 电压降额:实际工作电压建议不超过额定电压的80%(≤40V),延长产品寿命
  2. 温度限制:避免超过工作温度范围(-55℃~+125℃),否则容值变化超差
  3. 焊接工艺:采用回流焊(禁止手工焊),焊接温度需符合风华工艺规范(245℃±5℃,时间≤30s)
  4. 储存要求:常温干燥环境(≤60%RH)储存,开封后尽快使用(建议12个月内),避免受潮导致焊接爆浆
  5. PCB布局:避免靠近发热元件,减少热应力对电容的影响

该产品凭借成熟的工艺与稳定的性能,成为消费电子及通用工业领域的主流选型之一。

Sourcing availability signal

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.

The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
